The three levels of an earnings season
Most retail attention stays at level one: individual companies reporting beats or misses. The bigger trades are at levels two and three. Sector aggregates reveal whether banks, tech, energy, or consumers are leading the cycle — driving rotation flows that often last weeks beyond the report dates. The index aggregate (S&P 500 EPS growth rate and forward guidance composite) is itself a macro release: it tells you whether 'the economy through the lens of corporate America' is accelerating or decelerating.
Beats, misses, and guidance: which one matters
In aggregate, around 75% of S&P 500 companies beat consensus EPS in any given quarter — analysts are systematically too conservative. So the beat itself isn't a signal; the magnitude relative to history is. What moves stocks most is forward guidance: companies that raise full-year guidance get rewarded; companies that lower it get punished. A 'beat-and-lower' (beat the quarter, lower the year) is a frequent pattern that produces an initial rally and a multi-day reversal.
- →Beat magnitude vs history: Compare to the rolling 4-quarter beat rate — is this quarter unusually strong or just normal?
- →Revenue vs EPS: Top-line beats matter more than bottom-line — EPS can be financially engineered, revenue can't.
- →Forward guidance: The single highest-impact variable on the post-print move.
- →Margin trajectory: Quarter-over-quarter margin change tells you about input costs and pricing power.
Sector aggregates and rotation
The first 2-3 weeks of earnings season report different sectors in sequence: financials and consumer discretionary early, tech mid-season, retail and utilities late. The early reports set expectations for the late ones. If banks report strong loan demand and low credit losses, it suggests consumer health that flows through to discretionary stocks reporting next. If energy companies cut capex guidance, it signals demand worry that hits industrials. These cross-sector reads drive much of the rotation flow that defines the post-earnings tape.
Macro signals from the aggregate
The S&P 500 aggregate earnings number is reported by FactSet and Refinitiv each Friday during the season. A year-over-year aggregate EPS growth rate above 8-10% is consistent with mid-cycle expansion; below 0% is consistent with recession. Forward 12-month consensus EPS, when revised lower in aggregate by more than 3% during a season, is one of the most reliable recession leading indicators. The Fed watches this. The credit market trades it. Equity index pricing converges on it over 6-12 month windows.
How earnings interact with rates
Earnings season and Fed policy interact through two channels. The earnings cycle drives margins, which drive corporate hiring and inflation. The Fed responds to inflation with rate decisions. Strong earnings season → strong margins → Fed less likely to ease → higher rates → discount-rate headwind for stocks. The 'good news is bad news' dynamic of strong-earnings-into-hawkish-Fed is one of the most counterintuitive features of late-cycle markets, and it explains why the S&P can sell off on a 75% beat rate.
